C164SL8RMCAHXUMA3

Overview

The C164SL8RMCAHXUMA3 is a member of the Infineon C166 family, specifically the C164CI derivative series. It is a 16-bit single-chip CMOS microcontroller designed for cost-sensitive applications. The device integrates a high-performance CPU with a 4-stage pipeline, achieving an instruction cycle time of 80 ns at a 25 MHz clock speed. Key on-chip resources include 2 KBytes of Internal RAM (IRAM), 2 KBytes of Extension RAM (XRAM), and up to 64 KBytes of on-chip program Mask ROM or OTP memory. Peripheral modules feature an 8-channel 10-bit A/D converter and an 8-channel General Purpose Capture/Compare Unit (CAPCOM2).

Feature Summary

• Integrates a 16-bit CPU with a 4-stage pipeline architecture supporting single-cycle context switching.
• Includes on-chip PLL for flexible clock generation with multiple frequency factors.
• Features an 8-channel interrupt-driven single-cycle data transfer facility via the Peripheral Event Controller (PEC).
• Provides enhanced boolean bit manipulation facilities and register-based design with multiple variable register banks.

Applications

• Cost-sensitive embedded control systems
• Industrial automation controllers
• Automotive body electronics

Procurement Notes

Verify the specific suffix 'HUMA3' against official Infineon documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm that the 'C164SL' designation aligns with the required 64 KByte Mask ROM capacity. Ensure the operating temperature range matches the industrial specifications defined in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 16-bit architecture with high peripheral integration is required for budget-conscious designs. The C164CI derivatives offer a balance of processing power and I/O capabilities. Consider the available on-chip memory sizes and the specific need for the CAPCOM2 and ADC peripherals when evaluating alternatives within the C166 family.

Part Context

This part belongs to the C166 family of 16-bit microcontrollers, which are widely used in automotive and industrial applications. The C164CI series specifically targets cost-sensitive markets by combining high CPU performance with essential peripheral functionality. The architecture supports complex operations through its pipeline design and extensive interrupt handling capabilities.

Replacement Considerations

Check for direct pin-compatible upgrades within the C166 family, such as variants with larger memory capacities or different package options. Verify if newer generations from Infineon offer backward compatibility while providing improved performance or additional features.
